Unconventional Mac app categories gain momentum: diagrams, wallpapers, and document workflows

Unconventional Mac app categories are gaining momentum, and a quartet is showing there’s more to Mac and iOS apps than utilities. Meet SankeyChart, Vidwall Hub, CamScan, and Demofy—niche tools turning diagrams, wallpapers, and demo workflows into everyday workhorses.

• SankeyChart — a macOS app to build interactive Sankey diagrams without code. Import data from CSV, JSON, or Excel, drag to rearrange nodes and flows, and export to SVG, PNG, or HTML/JS for embedding ^[1].

• Vidwall Hub — imports videos (mp4, mov) into the system wallpaper service to be used as lock-screen animations; macOS sandbox limits prevent true dynamic lock screens, so it’s a standalone helper for the video-to-wallpaper workflow; not open-source, with downloads/issues hosted on GitHub ^[2].

• CamScan — in a big update: Document Signature and PDF Import Support; Image Editing Tool upgrades; performance and bug fixes; a fresh app icon rounds out the update ^[3].

• Demofy — iOS App Mockup & Demo Generator for showcasing apps; born from a hackathon, helps record from the iOS simulator, place the screen inside an iPhone frame, customize the background, and trim video ^[4].

These niche tools show the Mac and iOS ecosystems are embracing diagrams, wallpapers, and lightweight workflows—watch for more quirky productivity apps.
